Application filed February 23, 1917. Serial No. 150,568.

To all whom t may concern: l

Be it known that I, BERNHARD TRosKY, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Bazor-Stropper, of which the following is a full, clear, and exact description.

This invention relates to razor stroppers and has to deal particularly with improvements in stroppers .of that type disclosed in United States Letters Patent Number 1,213,556, granted to me on the 23rd day of January, 1917.

The invention has for its general objects to improve the construction of the bladeholding means whereby safety razor blades of various sizes, shapes and designs can be effectively held in proper position for coaction with the stropping rolls or elements.

A more specific object of the invention is the provision of a blade-holding device which embodies a plurality of blade-clamping hooks, one or both of which are movably mounted, and the hooks are normally urged toward each other by spring means, whereby the hooks will firmly grip a blade, they said hooks being mounted on a support which is in permanent cooperative relation with the stropping rolls.

Still another object of the invention is the provision of blade-engaging lugs 'or stops which cooperate with the hooks to more firmly hold certain types of blades.

W ith such objects in view, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and vclaims appended hereto.

In the accompanying drawing, lwhich illustrates one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in all the views,

Figure 1 is a horizontal section of the stropper on the line 1 1, Fig.r3, with portions of the blade-holding means in section;

Fig. 2 is a bottom plan view of the bladeholding means;

Fig. 3 is a transverse section on the line 3 3, Fig', 1;

Fig. 4 is a sectional view on the line 4 4, Fig. 1;

Fig. 5 is a sectional view on the line 5 5, Fig. 1;

Fig. 6 is a fragmentary sectional view similar to Fig. 3, showing a Gillette blade Y `blade-gripping hooks.

Referring to the drawing, A designates the casing of the stropper, which, in the present instance, is shown of upper and lower sections 1 and 2 hingedly connected together at a, and each section has a frame B, the end plates 3 ofwhich carry rotatable alternately acting stropping elements C. These elements are connected together by gears l, and on one of the elements is an operating crank 5.

rlhe frame B in the lower section has a horizontal plate or bar 6 which is adapted to support a blade in eoperative relation with the stropping elements C, and if desired the frame B in the upper section may have a matching plate or bar 7 to grip the top of the blade resting on the lower plate 6, as shown in Figs. 3'and 6, wherein the blades are designated D and E, respectively. The bars 6 and 7 have longitudinal `portions 8 and 9 relatively disposed so that one portion is out of the plane of the other. ln other words, the portions 9 are spaced farther apart than the portions 8 when the stropper casing is closed, as in Fig. 3, and between the portions 9 the enlarged space accommodates the reinforcing backing d of the blade'D. By arranging the portions 3 and 9.of eachblade-engaging plate in different levels a longitudinal shoulder 10 is provided so as to facilitate the proper positioning of the blade D.

A pair of oppositely disposed blade-gripping hooks 11 and 12 are associated with the portion 8 of the lower plate 6. Each hook comprises a flat body 13, and on one end thereof is a bent-back member forming the bill 14. T he bodies 13 lie under the portion 8 of the plate 6, such plate having recesses 15 through which the bills of the hooks project upwardly. The body portions ofv the hooks are supported in position by a supporting plate 16 constructed as shown in Fig. 8 and having apertures 17 into which Vthis purpose a helical spring 19 is connected with the body 13 of the hook 12, there being lugs 20 and 21 on the hook 12 and plate 16, respectively. A second helical spring 22 has its ends connected With lugs -23 and on the pla-te 16 and hook 11, re-

spectively. "N hen the hooks 11 and 12 are spread apart the springs are extended, and when the hooks are rele 'ed they move toward each other. For short blades only one hoch', say the hook 12, n'inst be moved outwardly so `as to permit a blade to be inserted, one end ofthe bl. le being placed under the hook 11, and with the blade resting on the plate 6, the hook 12 is released and its spring causes the said hook to move inwardly and gripthe blade F or long blades, as the Gillette blade E, indicated by dotted lines, Fig. 1, both hooks 11 and 12 are extended. To facilitate the insertion of the blade the lioolr12'is capable of being held in its outermost position byl means ot a catch 25, Figs. -l :and 7, which is adapted to be engaged in a recess 26 in the bottom ot the hook 12, the hook 12 having a slight resiliency so as to permit the hook to be engaged with or disengaged from the catch 25. fis shown in Figs. 3 and 6, the bodies 13 of the hooks are conned between the edge of the portion 9 of the plate' and the depending flange 27 on the same plate. VVThe outer corners of the lower plate 6 have upstanding lugs 2S Which cooperate with the hooks 11 and 12 for holding steady a Gillette blade, as shown in Fig. 1. To facilitate the insertion and removal of a blade, the plate 6 has a central recess 29 cut in its front edge, and the cent Wall 30 of the easing has a recess 31 for the same purpose. To properly position the blade a ylinger or indicator 32 is formed on one Wall of the casing, as shown in F ig. l, and the inner edge of the blade is brought into alinement With this indicator so that the said inner edge of the blade Will be in stropping relationto the stropping element.

F rom the foregoing description taken in connection with the accompanying drawing, the advantages or the construction and method of operation kWill be readily understood by those skilled ,inV the art to Which the invention appertains, and While l have described the principle oi' operation, together with the device Which 1 noiv consider to be the best embodiment thereof, l desire to have it understood that the device shown is merely illustrative and that such changesI may be made when desired as fall Within the scope of the appended claims.

Having thus described my invention, I claim as new and desirev to secure by Letters Patent:

1. A stropper comprising a. supporting structure, stropping means thereon, a plate lor supporting aiblade, :relatively movable hooks associated With the plate yfor gripping the ends oi the .blade,.and'xed members associated with the plate for engaging the ends oi2 the blade.

2. A stropper comprising a supporting structure, stropping means thereon, a plate for supporting a blade, relatively movablev hooks associated with the plate for gripping the ends of1 the blade, andv fixed members associated with the plate'for engaging the ends of the blade, said hooks being disposed to engage the blade at points between the edge being sharpened and the outer corners or the blade.

3. A stropper comprising Va supporting structure composed oi' relatively lmovable sections, coacting stropping means: mounted in the respective sections, plates `on'the sections for gripping opposite sides of a blade, relatively movable hooks on one of the plates iler gripping the ends of the blade, and means for moving the hooks tovvard each other.

A stropper including stropping elements, a pair of relatively movablev bladegripping hooks,spring means for urging the hooks toward each' other, .and a catch With which one of the hoo ts releasably engages lor holding the hooks separated for receiving between them the blade to be sharpened.

A sti-opper including a supporting structure, stropping means thereon, a bladeholding plate having different portions on dilierent levels, a second plate fastened te the 'Erst-mentioned plate, blade-gripping hooks disposed with their bodies between the second-mentioned plate and one ofthe portions ot the first-mentioned plate, and spring means urging the hooks toward each other. .6. A stropper comprising a supporting structure, stropping means therein, a pair 0i plates fastened together, and movable meansl held between the plates and having portions bent into hook bills projecting from the plates to grip the ends oit a blade resting on one or' the plates.
